1. Lana Del Rey

Lana performed at a pre-wedding party for Kim Kardashian and Kanye West’s May 2014 nuptials. The “Summertime Sadness” singer brought her dulcet tones to KimYe’s bash at the Palace of Versailles in France and despite the rumors of Lana getting millions of dollars for the gig, she says, she did it for free.
